Specification of Letters Patent. Patented N 30, 1920.

Application filed. February 12, 1919. Serial No. 276,458.

To all whom it. may concern: I Be it known that I, CHAnLns LEWIS Hoorns, a citizen of the United States, re-

siding at San-Diego, in the county of San Diego and State of California, have invented certain new and useful Improve.- ments in Submerged Piles andMeans for Constructing the Same, of which the following is a specification. l

My invention relates toa pile structure and more particularly to a meansfor cover.- ing wooden or other similar piles with concrete to prevent their deterioration in the water by teredo and the like or for pile structure formed by'the use of an ordinary pile used as a gu se pilefor placing and properly positioning the. constructed pile and then removing the same and filling the interior with concrete and the objects of my invention are first, to provide a pile structure of this class in which a .pile is driven as a core and a plurality of annular reinforced concrete form members are positioned around said pile and the space between the pile and saidconcrete form member filled, second, to provide a pile structure of this class in which an ordinary pile is driven and a pluralityv of annular reinforced concrete form members positioned around said pile then said pile is removed and the interior filled with concrete, third, to provide means for covering piles already driven with a concrete layer for preserving the submerged portion of said pile, fourth, to provide a -means for covering the submerged portion of a pile with cement while said pile is submerged and in which the mold in which the concrete is poured is left in position and forms a part of the concrete. covering, fifth, to provide a pile structure of this class in which a plurality of annular reinforced concrete members with interlocking edges are secured together forming a pile of the pedestal pile form which maybe either left hollow or filled internally with concrete after the same is sunk to position, and sixth,

' to provide a pile structure of this class which is very simple. and economical of construction, durable, easy to install andscribed in detail and particularly set forth in the appended claims reference being had to the accompanyingdrawings and to the characters of reference thereon which form a aart of this application in which:

igure 1 is a longitudinal sectional View of one of my'plle structures showing the sectional View along the line 2-2 of Fig. 1; Fig. 3 is a longitudinal sectional View of my structure as applied to a pile partially destroyed by teredo. or the like; Fig. 4 is a detailed fragmentary sectional view of the lower end of a pedestal pile structure in' a slightly modified'form from that of Figs. 1, 2 and 3 and Fig. 5 is a top view thereof. q

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings. i

The ordinary pile core portion 1, annular monolithic mold member 2, cement body 3, and jet 4 constitute the principal parts and portions of my pile structure.

. The pile .1 isan ordinary pile usually wooden which is driven or jetted into the ground in the position desired and over the top of this pile and passes down and over the same are a plurality of annularmono lithic concrete members 2 provided with interlocking edges 2 so that these annular members interlock with each other thus forming a concrete shell spaced apart from the outer surface of the pile which serves as a mold. Each of these members 2 are provided with reinforcing bars 2 and 2 and the lugs 2 adapted for the rods 2 and with other lugs 2 which are threaded to receive the threaded ends of the rods 2 for securing the separate members 2 together. The lower end of this shell is jetted into the earth some distance by means of the jet 4 thus forming a mold from some distance below the surface of the. earth to above the high water line and between the pile 1 and the shell formed by the member 2 concrete is poured filling said spaces thus forming a pile the submerged portion of which consists of a wooden or other pile as a core with concrete poured around the same and an outer surface consisting of a plurality of interlocked monolithic reinforced annular members.

In the form of structure shown in Figs. 4

and there is shown a pedestal pile which is constructed in a similar manner-except that the lower end is provided with an enlarged tapering concrete member 5 which is provided with a sharp edge 5 adapting it to enter the earth when the ground is taken out from the inside of the member 5. This member tapers at 5 and on its upper edge it is provided with an extended portion 5 which'interlocks with the annular member 2. This structure is constructed by first in an adjacent member.

driving a plurality of guide piles 6. In this form of construction the joints between the members 2 and the members 2 and 5 are made water tight by covering the edge surfaces with tar, oakum or other water tight substance and these members 2 and 5 are secured together by means of rods 2 which extend from one section to the other which is secured in one of said members and the one end of which is threaded to screw into a lug 2 which is embedded in the concrete It will be noted that these members 2 may be molded in any position 'desired'and transported to the place of use or they may be molded in position above the surface of the water and lowered into position and the different sections se- 7 cured together until the lower section 5 reaches the earth and is supported thereby after which it may be jetted some distance forming a coffer dam after which the inside (maybe cleaned or dug out and the same sunk to any position desired. It will be noted that these members 2 and 5 are each provided with suitable reinforcements to provide the proper strength for said members as hereinbefore described. I Though I have shown and described a plarticula'r construction, and certain modi cations thereof I do not wish to be limited to this particular construction, nor to the modifications thereof nor to the particular means for providing forms for producing the pilebut desire to include in the purview of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

It is obvious that with this construction,

there is provided a pile structure and means for forming a pile structure in the water in submerged position in which a concrete pile may be molded inposition in the water or a 'pile'driven as a core and-the same covered with a concrete covering or a'pile already driven and partially deteriorated may be reconstructed witha concrete covering and reinfo rcement, that the members 2 provide a shell mold into which theconcrete may be poured and permitted to set which remain in position as an additional outer covering for the pile, that the structure and means lithic, reinforced, plastic members positioned one above the other and provided with in ner and outer extended portions whereby they are interlocked with each other,'a rod secured to one of said members on the inner surface thereof, a lug secured to another of said members on the inner's'urface thereof adapted to receive said rod for securing said members rigidly together and concrete filling the space-between said core member and said'monolithic reinforced plastic members.

2. An apparatus of the class described, including a pile member driven into the earth, forming a core, a casing surrounding Sitld. core and spaced apart therefrom, consisting of a plurality of annular, monolithic, reinforced, plastic sections provided with annular inner extended flanges on their one end and with annular. outerextendedzfianges on their opposite ends so that whenthey are" placed end to end they interlockwith each other, a plurality of supports secured near one end of each of said sections andextending inwardly in said sections, rods mounted in said supports, other supports in said sections provided with threaded ends'adapted for the threaded ends-of the rods on an adjacent section whereby said sections are rigidly secured together andconcrete filling the space between said driven pile and said casing.

V In 'testimorgy whereof, I have hereuntoset my hand at CHARLES LEwIs HOOPESa an Diego, California, this 1st 7 day of February, 1919 Y
